Abstract: A display device that includes a substrate, a display element disposed on the substrate and having a pixel electrode, an emission layer, and an opposite electrode, an inorganic functional layer disposed on the opposite electrode and including a first element, and a thin-film encapsulation layer disposed on the inorganic functional layer, wherein the inorganic functional layer includes a first film and a second film disposed on the first film. In each of the first film and the second film, a stoichiometric ratio of the first element decreases as distance from the substrate increases. The first element may be one of silicon (Si), titanium (Ti), aluminum (Al), hafnium (Hf), indium (In), tin (Sn), chromium (Cr), manganese (Mn), iron (Fe), tantalum (Ta), zinc (Zn), and a combination thereof.

Abstract: A material-removing heater device including: a first terminal portion defining a first electrode; a second terminal portion defining a second electrode; and a heating portion which connects the first terminal portion to the second terminal portion, the heating portion heatable by a flow of electrical current from the first terminal portion to the second terminal portion to remove a portion of material of a display device. The heating portion defines a lower end surface of the material-removing heater device at which the material-removing heater device contacts the material of the display device, the heating portion disposes the lower end surface to have a concave shape, and the heating portion which is heated deforms the lower end surface from the concave shape to have a planar shape.
